Which Markdown flavor is rendered?

Rendering covers the widely used core plus common extensions like tables and fenced code blocks — closely matching what GitHub displays for READMEs.

Why does my table not render?

Markdown tables need a header separator row like | --- | --- | and matching pipe counts per row. A missing separator is the most common cause.

How do I add syntax highlighting to code blocks?

Add the language after the opening fence: ```python. The preview highlights recognized languages the same way GitHub does.

Is my text sent to a server?

No — rendering happens locally in your browser, so drafts and internal docs are safe to preview.
